The unrest, in communities from Minnesota to Washington state, is connected in each case to the ongoing battle over an oil pipeline under construction in North Dakota. He said the protest was a "stupid move" that did not accomplish its goal.

Ezra Miller said in the video: "As a gang of earth defenders, we want to send a big shout out to the Oceti Sakowin and those who stand with them in opposing the Dakota Access Pipeline".

According to David Archambault II, Chair of the Standing Rock Sioux, "Today's listening session is a critical opportunity to inform the process moving forward so that other tribes don't suffer the same losses as the Standing Rock Sioux Tribe".

A federal appeals court ruling Sunday cleared the way for work to resume on that land, which is near Lake Oahe. Work is still prohibited on corps land bordering and under the lake, which is a source of water for the tribe. Steve Sitting Bear, a spokesperson for the Standing Rock Sioux tribe, told NBC News that six people, including a child, suffered dog bites, and dozens were pepper-sprayed.

The protest has also received vocal support from Hollywood celebrities, including Leonardo DiCaprio and Susan Sarandon. He didn't have further details.

Woodley livestreamed the protest and her arrest on Facebook, showing police with armored vehicles and riot gear.

Pipeline company officials confirmed attempts in Minnesota and Montana, while the attempts in the other two states could not be immediately verified. She says the company temporarily shut down the lines.

She also said that she felt singled out of a big crowd of protestors "because I'm well known, because I have 40,000 people watching". Hammel says about 100 protesters held a "prayer ceremony" at a nonoperational construction site where the pipeline crosses Highway 6, about 45 minutes southwest of Bismarck. Dallas-based Energy Transfer Partners says it will start working again, but isn't saying exactly when.

Two campaigners chained themselves to construction equipment, according to the sheriff. The pipeline was scheduled to be in service by the end of the year, and the company hasn't said publicly that it expects that deadline to be delayed.

Standing Rock Sioux Tribe members will be among those set to participate in a listening session hosted by the Obama Administration.

The company's spokeswoman Vicki Granado declined to say exactly when construction of the $3.8bn, 2,500km pipeline - which will carry nearly half a million barrels of oil per day from North Dakota to IL - would resume.

Actress Shailene Woodley is facing 60 days behind bars and fines if she's convicted of criminal trespass and engaging in a riot.
